Geological vs archaeological debate over A ditch carved in the rock's origin. Geologist Robert Hill identified the formation as sandstone dikes - vertical sheets of sediment filling ancient cracks US Geological Survey and Smithsonian researchers in early 20th century concluded it was naturally formed disconnected sandstone veins In 1925, archaeologist Count Byron de Prorok examined the wall and became convinced it was a prehistoric man-made edifice
Scientists remain divided over A ditch carved in the rock's origin. Geologist Robert T. Hill in 1901 identified it as natural sandstone dikes—vertical sheets of sediment filling ancient cracks. In 1925, archaeologist Count Byron de Prorok declared it prehistoric man-made construction. In 1979, UT-Arlington's Kenneth Schaar confirmed natural formation, while 1996 architect John Lindsey argued it showed evidence of human engineering.
